1' 0 aZZ whom it may concern Be it known that L'ALBERT Hnnivms, acitizen of the United Kingdom of Great Britain and Ireland, and residentof Leytonstone, London, E. 11, England, have in vented certain new anduseful Improvements in and Relating to Valves and Caps for Drums and thelike Vessels, of which the following is a specification, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to a valve for use with vessels containingvolatile liquids or compressed gas and is of that type which comprises abody part fitted to the vessel and havin a valve in it capable of beingscrewed up and down (opened and closed) by a handle mounted in anotherpart pro vided with an outlet nozzle.

According to my invention the valve is provided with passages through itso positioned that when it is opened the gas or liquid will pass throughthese passages and out through the nozzle without the necessity oflifting the valve past the nozzle. The said passages also form a meansby which the handle or key can rotate the valve.

To protect the valve in transit the nozzle body part can be removedafter the valve has been screwed down and a cap or cover of known orconvenient kind screwed onto the body part containing the valve thusvery securely and doubly sealing the outlet from the vessel.

The removable part may have more than one nozzle and it or they may beused for both filling and emptying the vessel.

The construction according to the present invention can be so arrangedthat projecting portions such as are apt to get injured during transitof the containers are absent, and the fitting in ordinary cases willoccupy very little more room than the usual type of screw bung fitted todrums used for nonvolatile liquids.

An important feature of the construction according to the invention isthat the efi'ec tive portions of the valve are completely protected fromthe combined action of atrnos pherie air and moisture, and that theoperative portions of the valve are for the most part only applied whenthe valve is actually in use during the charging or emptying of thecontainer. This point is of importance in the case of valves forcontainers for corrosive materials as chlorine or sulphur dioxide.

is DRUMS AND THE LIKE V l An example of my invention is shown in theaccompanyingdrawing which is a central vertical section, and

a represents the portion of the arrangement permanently attached to thecontainer fitted internally with a plug whichmay be screwed down on tothe seating shown.

6 represents the replaceable fitting shown in position and comprisingthe operative portion of the valve and carrying an outlet connection j creprecsents the protecting cap which is interchangeable with b carryinga gasket to ensure a gastight joint.

The permanent fitting a. together with the plug, which screws down on tothe seating g enables the passage it to be opened or closed at will, asthe plug is externally threaded, and the fixture a is internallythreaded at e. The fixture a is externally threaded at (Z. so that thecap 0 or the interchangeable fit ting b may be screwed on at will. Inorder to permit a connection to be established to the inside of thedrum, it is necessary that provision be made for the fluid to pass theplug f when this is in the open position, and in this case holes 2' areprovided, three of which are shown. These holes 7, also serve to engagethe projections Z so that the plug may be raised and lowered by turningthe handle. The opening j is threaded to receive a suitable pipeconnection. The spindle passes through a small pack- 1ng box, so thatleakage during the period of operation of the valve is avoided. In orderto prevent leakage through the screw threads (Z, the cap 0 and theinterchangeable fitting Y) may be provided with asuitable packing ringm. During transit or during periods of storage, when it is not requiredto draw off the contents "from the containers, the cap 0 is screwed intoposition, and the effective portions of thevalve are thoroughlyprotected thereby, and absence of leakage assured. In such cases where alarge number of containers have to be dealt with, it will in general benecessary to provide for each container the permanent fittings a withthe internal plug 7 and the cap 0. It will, however not be necessary toprovide for each'container the portion as one fitting of thisdescription will will be sufiicient for charging and emptying a numberof containers.

lVhat I claim is A fitting for containers and the like, comprising avalve casing part adapted to be v cl fixed to the container, a valvemember threaded in said casing part, a valve carried by said valvemember and cooperating with a seat in said casing part, said valvemember being formed with longitudinally extended passages, a secondvalve casing part adapted for removable threaded connection with thefirst casing part and formed with an outlet, a valve operating membermovable in said second casing part and formed at the lower end withprojections adapted to en-
